SO4 yeast good stuff
SO4 yeast is sun up dependable. Ferments fast and drops like a rock. I typically use it to ferment american ale. Good flavor profile and fast fermentations.

Dependable Yeast, Better Price than S5
From the man of the family: I brew a lot of beer, mostly English-style red and amber ales. I look for a better price on bulk yeast and I trust the Safale brand. I've never had a batch fail -- not yet, knock on wood. My go-to yeast is usually Safale 5, but recently, for whatever reason, the price has gone up. I've often used #4 as well, and for my purposes, it does exactly the same good job. I'm ordering this product now because of the price difference. Recommended!

Great Yeast for a Great Price!
I have been purchasing yeast from Amazon for a couple of years now. I typically buy 3 packs and have brewed mostly with Safale US-05 as I typically brew American IPA's. I decided to try a little different flavor profile and went with the Safale S-04 and I'm not disappointed! This yeast ferments very quickly, within 3-5 days as opposed to 7-10 for US-05 and sedimentation is excellent. Beer is clear after a week in the fermenter or so, no secondary needed. It doesn't ferment as low as US-05 so if you're looking for a higher ABV, make sure you bump the grain bill up. Otherwise, I actually prefer the flavor of the S-04 to the US-05 in certain IPA recipes. Will definitely purchase again!

Works great
Bought this to re-pitch because some yeast that came in an extract kit got stuck. Did what it was supposed to. Hooray, beer!

Ginger beer!
Having a great time making ginger beer. 1.5lbs ginger. 5 lemons. 2.5 cups brown sugar. 1 packet Safale S-04. Sanitize everything. Boil all in about 1.5 gallons of water. Sanitize carboy. Add 1 gallon cold water. Add boiled ingredients. Add 3 more cups water. Store for 4-7 days. Bottle with 1 cup white sugar as a primer. We are loving it! Made 6 batches now. We feel it's much healthier than what's on the market...
